Preheat the oven to 350°F.
Butter a 4×8-inch loaf pan.
Mash the ripe bananas with a fork in a mixing bowl, until completely smooth.
Stir in the melted butter.
Add the the baking soda and pinch of salt.
Gradually stir in the sugar, beaten egg, cinnamon and vanilla extract then mix in the flour.
Mix pecans into batter.
Pour the batter into your buttered loaf pan.
Bake for 50 minutes to 1 hour at 350°F. (I test by inserting toothpick into center at 50 min. to see if it comes out clean.)
Remove from oven and cool on a rack.
